CONDITION
For customer concerns of no or poor outgoing sound from the Bluetooth systems there are diagnostics in the
repair manual which can be performed to diagnose the condition.
RECOMMENDATIONS
When diagnosing potential concerns with the vehicle’s microphone, in the repair manual go to the problem
symptoms table for the audio system and follow the diagnostics for “Other caller cannot hear your voice, or your
voice is distorted”.
For vehicles equipped with the navigation system go to the problem symptoms table and follow the diagnostics
for “Caller’s voice (your voice) is interrupted by noise or sound quality is poor”.
An example of the problem symptoms table for the 2016 Camry Navigation System is shown below.
